B. Zvinodiwa zvezvinhu zvakasiyana mugiredhi rekudya
Zvinhu zvakasiyana-siyana zvemapepa makapuinoda nhevedzano yebvunzo uye ongororo mune chikafu giredhi certification. Izvi zvinogona kuve nechokwadi chekuchengetedza kwayo uye hutano mukusangana nechikafu. Maitiro echikafu giredhi certification anogona kuve nechokwadi chekuti zvinhu zvinoshandiswa mumapepa makapu zvakachengeteka uye hazvina kukuvadza, uye zvinosangana nezviyero uye zvinodiwa pakubata chikafu.
1. Chikafu giredhi certification process yekadhibhodhi
Sechimwe chezvinhu zvikuru zvekapu yemapepa, kadhibhodhi inoda chikafu chegiredhi certification kuti ive nechokwadi chekuchengetedza kwayo. Iyo yechikafu giredhi certification process yemakadhibhodi inowanzo sanganisira anotevera matanho:
a. Raw material kuyedzwa: Kemikari kuumbwa kwekuongorora kwekadhibhodhi raw materials. Izvi zvinovimbisa kuti hapana zvinhu zvinokuvadza zviripo. Zvakadai sesimbi dzinorema, chepfu, nezvimwe.
b. Kuyedzwa kwekuita kwemuviri: Ita mechanic performance test pamakadhibhodi. Zvakadai sekusimba kwesimba, kudzivirira mvura, nezvimwewo Izvi zvinovimbisa kugadzikana uye kuchengeteka kwekadhibhodhi panguva yekushandiswa.
c. Kutama bvunzo: Isa kadhibhodhi mukubatana nechikafu chakaedzerwa. Tarisa uone kana zvinhu zvichipinda muchikafu mukati menguva yakati kuti uongorore kuchengetedzeka kwezvinhu.
d. Oiri humbowo bvunzo: Ita coating test pamakadhibhodi. Izvi zvinovimbisa kuti mukombe wepepa une mafuta akanaka ekupikisa.
e. Microbial kuyedzwa: Ita microbial bvunzo pamakadhibhodi. Izvi zvinogona kuve nechokwadi kuti hapana kusvibiswa kwehutachiona senge mabhakitiriya uye mold.
2. Chikafu giredhi certification process yePE coated paper
PE yakavharwa bepa, seyakajairwa kupfekedza zvinhu zvekapu yemapepa, inodawo chitupa chegiredhi rekudya. Yayo certification process inosanganisira anotevera matanho makuru:
a. Material kuumbwa kuyedzwa: Ita kemikari kuumbwa kwekuongorora pane PE coating zvinhu. Izvi zvinovimbisa kuti haina zvinhu zvinokuvadza.
b. Kutama bvunzo: Isa PE yakavharwa bepa inosangana nechikafu chakaedzerwa kweimwe nguva yenguva. Izvi ndezvekutarisa kana paine zvinhu zvapinda muchikafu.
c. Thermal kugadzikana bvunzo: Tevedzera kugadzikana uye kuchengetedzeka kwePE coating zvinhu pasi pekushisa kwakanyanya.
d. Chikafu chekubata bvunzo: Bata PE yakavharwa bepa nemhando dzakasiyana dzechikafu. Uku kuongorora kukwana kwayo uye kuchengetedzwa kwezvikafu zvakasiyana.
3. Chikafu giredhi certification process yePLA biodegradable materials
PLA biodegradable zvinhu ndezvimwe zvinomiririra zvakatipoteredza zvine hushamwari zvinhu. Inodawo chitupa chegiredhi rekudya. Iyo certification process inosanganisira anotevera matanho makuru:
a. Material kuumbwa kuyedzwa: Ita ongororo yekuumbwa pazvinhu zvePLA. Izvi zvinogona kuve nechokwadi chekuti zvigadzirwa zvinoshandiswa zvinosangana nezvinodiwa zvegiredhi rekudya uye hazvina zvinhu zvinokuvadza.
b. Degradation performance bvunzo: Tevedzera nharaunda yechisikigo, edza chiyero chekudzikira chePLA pasi pemamiriro akasiyana uye kuchengetedzeka kwezvinhu zvinosvibisa.
c. Kutama bvunzo: Isa zvinhu zvePLA zvakasangana nechikafu chakaedzerwa kweimwe nguva yenguva. Izvi zvinogona kutarisa kana chero zvinhu zvakatamira muchikafu.
d. Kuyedzwa kweMicrobial: Ita microbial bvunzo pane PLA zvinhu. Izvi zvinovimbisa kuti haina kusvibiswa nehutachiona senge mabhakitiriya uye mold.
